I gotta say, being a newcomer to warhammer everything seems pretty equal to me. My list is a mishmash Aelfs that seemed cool to me, no synergy or abilities to speak of and most of my games have been pretty close. from everything I've heard and read, you can take just about anything and give anyone a run for their money if you play it right. The difference between winning and losing is mostly just a few lucky rolls and knowing the tactics of your list.
